First claim
Opening claim text (preview).
What is claimed is: 1 . An oil delivery system, comprising: a bearing housing comprising an oil delivery cavity; a bearing comprising an outer ring contacting the bearing housing; and a passage formed through the outer ring. 2 . The oil delivery system of claim 1 , wherein the passage is aligned with the oil delivery cavity. 3 . The oil delivery system of claim 1 , wherein the passage is configured to deliver oil to a surface opposite the passage at an angle between 0 degrees and 90 degrees relative to the surface. 4 . The oil delivery system of claim 1 , further comprising a clocking mechanism configured to align the passage and the oil delivery cavity. 5 . The oil delivery system of claim 1 , wherein the passage further comprises an inlet formed in the outer ring. 6 . The oil delivery system of claim 5 , wherein the passage further comprises a first passage formed into a spot face of the inlet and in the outer ring. 7 . The oil delivery system of claim 6 , wherein the passage further comprises a nozzle passage formed through the first passage and in the outer ring. 8 . The oil delivery system of claim 7 , wherein a portion of the outer ring is bored to create a surface defining an outlet of the nozzle passage. 9 . The oil delivery system of claim 1 , wherein the oil delivery cavity comprises a buffer plenum. 10 . The oil delivery system of claim 9 , wherein the buffer plenum comprises a cylindrical geometry. 11 . A bearing, comprising: an outer ring; and a passage formed through the outer ring. 12 . The bearing of claim 11 , wherein the outer ring further comprises a clocking mechanism configured to align the outer ring in response to installation. 13 . The bearing of claim 11 , wherein the passage further comprises an inlet formed in the outer ring. 14 . The bearing of claim 13 , wherein the passage further comprises a first passage formed into a spot face of the inlet and in the outer ring. 15 . The bearing of claim 14 , wherein the passage further comprises a nozzle passage formed through the first passage and in the outer ring. 16 . The bearing of claim 15 , wherein a portion of the outer ring is bored to create a surface defining an outlet of the nozzle passage. 17 . A bearing outer ring, comprising: a cylindrical body comprising an outer diameter and a sidewall adjacent the outer diameter; and a passage formed through the cylindrical body, the passage extending from the outer diameter to the sidewall. 18 . The bearing outer ring of claim 17 , wherein the cylindrical body further comprises a clocking mechanism configured to align the cylindrical body in response to installation. 19 . The bearing outer ring of claim 17 , wherein the passage further comprises a nozzle passage formed in the cylindrical body. 20 . The bearing outer ring of claim 19 , wherein a portion of the cylindrical body is bored to create a surface defining an outlet of the nozzle passage.
